CARBON DIOXIDE SEPARATION MEMBRANE

摘要

The present invention discloses a membrane for selectively separating carbon dioxide from a gas mixture (e.g. with methane), having excellent heat resistance, durability and anti-chemical agent resistance (anti-corrosion resistance) formed from a sol comprising polymerisation a tetraalkoxysilane and a methyl trialkoxysilane and resulting in a polysiloxane having uniformly dispersed methyl groups.
